Mary Kay Cabot of Cleveland.com reported the diagnosis on Monday after Thomas' MRI. Adam Schefter of ESPN later reported Thomas faces a six-to-nine month recovery, "allowing him time to decide whether he wants to continue playing."

Earlier in the day, Thomas was asked about his future, saying he didn't know if his career was over and it was best to discuss it in the offseason.

The injury ends Thomas' streak of playing 10,363 consecutive snaps on offense:

He has been with Cleveland his entire career since being selected with the No. 3 overall pick in the 2007 draft and was yet to miss a game entering the 2017 campaign. He has been incredibly durable, and the Browns don't know what it is like to play without Thomas' presence along the offensive front since he entered the league.

Thomas isn't just durable, he is one of the best linemen in the league. The offensive tackle is a 10-time Pro Bowler and six-time First Team All-Pro member and earned the Bruce Matthews Award as Pro Football Focus' best offensive lineman in the NFL for the 2015 campaign, per Ben Stockwell of PFF.
